а не чисто номер

Вот код где проаеряет отмеченые
[php]public function Exsel() {
$this->load->language('sale/order');

$this->data['title'] = $this->language->get('heading_title');

if (isset($this->request->server['HTTPS']) && (($this->request->server['HTTPS'] == 'on') || ($this->request->server['HTTPS'] == '1'))) {
$this->data['base'] = HTTPS_SERVER;
} else {
$this->data['base'] = HTTP_SERVER;
}



$this->load->model('sale/order');

$this->load->model('setting/setting');

$this->data['orders'] = array();

$orders = array();

if (isset($this->request->post['selected'])) {
$orders = $this->request->post['selected'];
} elseif (isset($this->request->get['order_id'])) {
$orders[] = $this->request->get['order_id'];
}

foreach ($orders as $order_id) {
$order_info = $this->model_sale_order->Exsel($order_id);

а какой результат должен быть то ?

Но допустим chekbox мы отмечает 5 строечек ,и на exsel они должны высвечится.А оно только из 5 мне родну строечку дает

ну так передай выбранные chekbox в файл массивом.

<input type="checkbox" name="order_id[]" value="1">
<input type="checkbox" name="order_id[]" value="2">

if (isset($_POST['order_id'])) {
     $order_id = $_POST['order_id'];
     $order_info = $this->model_sale_order->Exsel($order_id);
}

и в запросе тащи свои данные о товаре и все остальное

$sql = "
SELECT 
	p.*,
	o.*, 
	c.iso_code_2 AS c_iso_code_2, c.iso_code_3 AS c_iso_code_2,
	c2.iso_code_2 AS c2_iso_code_2, c2.iso_code_3 AS c2_iso_code_2,
	z.`code` AS z_code,
	z2.`code` AS z2_code
FROM 
	`" . DB_PREFIX . "order_product` p
LEFT JOIN
	`" . DB_PREFIX . "order` o ON o.id = p.order_id
LEFT JOIN
	`" . DB_PREFIX . "country` c ON c.country_id = o.payment_country_id
LEFT JOIN
	`" . DB_PREFIX . "country` c2 ON c2.country_id = o.shipping_country_id
LEFT JOIN
	`" . DB_PREFIX . "zone` z ON z.zone_id = o.payment_zone_id
LEFT JOIN
	`" . DB_PREFIX . "zone` z2 ON z2.zone_id = o.shipping_zone_id
WHERE 
	p.order_id IN (" . implode(',', $order_id) . ")
";

и так далее

Вот тут уже было

<input type="checkbox" name="selected[]" value="<?php echo $order['order_id']; ?>" checked="checked" />
                <?php } else { ?>
                <input type="checkbox" name="selected[]" value="<?php echo $order['order_id']; ?>" />
                <?php } ?></td>

<a onclick="$('#form').attr('action', '<?php echo $exsel; ?>'); $('#form').attr('target', '_self'); $('#form').submit();" class="button"><?php echo $btn_exsel; ?>

Вот кнопка

Вот я код уменьшил

$this->load->language('sale/order');

		$this->data['title'] = $this->language->get('heading_title');

		if (isset($this->request->server['HTTPS']) && (($this->request->server['HTTPS'] == 'on') || ($this->request->server['HTTPS'] == '1'))) {
			$this->data['base'] = HTTPS_SERVER;
		} else {
			$this->data['base'] = HTTP_SERVER;
		}

	

		$this->load->model('sale/order');

		$this->load->model('setting/setting');

		$this->data['orders'] = array();

		$orders = array();

		if (isset($this->request->post['selected'])) {
			$orders = $this->request->post['selected'];
		} elseif (isset($this->request->get['order_id'])) {
			$orders[] = $this->request->get['order_id'];
		}

		foreach ($orders as $order_id) {
			$order_info = $this->model_sale_order->Exsel($order_id);
		}
			

}
